Abstract
The invention discloses a kind of anti-rotation device for bolt interlocking, including anti-rotation pad body, the anti-rotation pad body sets elongated shape, its upper surface offers a groove, the width of the groove is adapted with the head across flats of bolt, and the screw that several threaded portions for bolt are fed through is offered in the groove.The present invention can it is limited in operating space in the case of, quickly and efficiently fastening bolt connect.
Description
Technical field
The present invention relates to the mechanical structure on crane, suitable for the not easy-operating position of narrow space, more specifically,
It is related to a kind of anti-rotation device for bolt interlocking.
Background technology
In handling machinery metal structure, subregion needs the mode being connected by screw bolts, most common at present
Bolt connection for bolt 1, nut 2, packing ring 3 as shown in figure 1, support the use.When mounted, according to relevant criterion, operating
In the case that space is enough, typically using the head of fixing bolt 1, nutting 2 is then applied to complete to install.
But in handling machinery metal structure, it is narrow and small also there are some locational spaces for needing to be connected by screw bolts
Situation (scope as shown in label a in Fig. 2).For example, in the case that the head of bolt 1 is in casing 4 (as shown in Figure 3),
When single packing ring 3 is respectively configured in each bolt 1, there will be bolt 1 if the not head of fixing bolt 1, during nutting 2 and follow and revolve together
Situation about turning；But to the head of fixing bolt 1, because the operating space in casing 4 is limited, be not easy to very much to put some to
The instrument on the head of fixing bolt 1 so that the operation is difficult to, it is necessary to completed, for example used using some interim measures
Off-gauge aid, the head of bolt 1 is fixed, after waiting fastening, then such aid removed, therefore, not only
The constructing operation at scene is not easy to, is even more wasted time and energy.
In some current existing Anti-rotating grommets, as disclosed in Publication No. CN 204164139U " a kind of Anti-rotating grommet ",
Including by pressure pad circle, in addition to turn card, at least two, the anti-rotation card, which is used to match, to be used, match two anti-rotation cards using it
Between into the straight angle and positioned at by pressure pad circle periphery, with integral by pressure pad cast, anti-rotation card can bend along respective base, pairing use
Two anti-rotation card bases between be smaller than nut circumscribed circle, for preventing cap rotation.But above-mentioned Anti-rotating grommet is
With monomeric form, when being attached than being more suitable for single bolt, if when one group of bolt is attached, above-mentioned monomer is prevented
Turning packing ring cannot also be applicable.
The content of the invention
For drawbacks described above present in prior art, it is an object of the invention to provide a kind of anti-rotation for bolt interlocking
Device, can it is limited in operating space in the case of, quickly and efficiently fastening bolt connect.
To achieve the above object, the present invention adopts the following technical scheme that：
A kind of anti-rotation device for bolt interlocking, including anti-rotation pad body, the anti-rotation pad body set elongated
Shape, its upper surface offer a groove, and the width of the groove is adapted with the head across flats of bolt, opened in the groove
The screw being fed through provided with several threaded portions for bolt.
Described screw quantity at least two.
In above-mentioned technical scheme, a kind of anti-rotation device for bolt interlocking provided by the present invention, without using
Instrument fixing bolt head, only it need to apply nutting, you can realize being fastenedly connected for bolt, so as to simplify installation process, reduce
The workload at scene, alleviates operating personnel's operation intensity, so as to improve efficiency of assembling.Also, more screws of the present invention are set
Put, interlocking effect also with bolt, after bolt connection installation, equally also there is the function of preventing that bolt from rotating.

Embodiment
Technical scheme is further illustrated with reference to the accompanying drawings and examples.
Incorporated by reference to shown in Fig. 4 to Fig. 9, a kind of anti-rotation device for bolt interlocking provided by the present invention, according to bolt 1
The hexagonal characteristic in head, the anti-rotation device to match with it is set.The anti-rotation device includes anti-rotation pad body 5, the anti-rotation
Pad body 5 sets elongated shape, and one of groove 6, the width and spiral shell of the groove 6 are offered in the upper surface of anti-rotation pad body 5
The hexagonal head across flats of bolt 1 are adapted, and offered in the groove 6 several can wear for the threaded portion of bolt 1
The screw 7 crossed.During installation, the threaded portion of bolt 1 is first fed through corresponding screw 7, the head of bolt 1 is placed in groove 6
It is interior, also, an opposite side of the hexagonal head of bolt 1 is just stuck in the edge of groove 6, you can realize bolt 1 and anti-rotation advance capital for
Relatively-stationary relation is kept between body 5.Then nutting 2 is applied according still further to the installation steps of routine, you can complete the company of bolt
Installation is connect, so just can be suitably used for the small space region that setting tool is put in any inconvenience.
Preferably, the described quantity at least two of screw 7, eight screws 7 are employed in the present embodiment.In multiple bolts
In the case that 1 is one group, can be without the use of any additional means and measure, so that it may make all bolts 1 and anti-rotation pad body 5 it
Between keep relatively-stationary relation, and between the bolt 1 on same anti-rotation pad body 5 also tool interlocking the effect of.
It is made preferably, described anti-rotation pad body 5 uses with steel construction identical material.
When in summary, using installation bolt of the present invention, it is only necessary to each bolt head is positioned in groove, is not required to make again
With any additional means and measure with regard to energy fixing bolt head, nutting is applied according to conventional installation steps, you can realize that bolt connects
The installation connect, so as to simplify installation process, the workload at the scene of reducing, improve efficiency of assembling.
Those of ordinary skill in the art it should be appreciated that the embodiment of the above be intended merely to explanation the present invention,
And be not used as limitation of the invention, as long as in the spirit of the present invention, the change to embodiment described above
Change, modification will all fall in the range of claims of the present invention.
